Serial No. 723,408.

To all whom 2'25 may concern Be it known that I, JOHN C. HOGAN, a citizen of the United States of America, residing at Goodwin, in the county of Dakota and State of Nebraska, have invented new and useful Improvements in Douhle-Door- Locking Devices, of which the following is a specification.

This invention relates to improvements 1n double door locking devices and has pa I'titilb lar application to a device of the class described -for use on railway car doors.

In carrying out the present invention, it is my purpose to provide a locking devlce for railway car doors whereby the doors may be securely locked in closed position and which will embrace the desired features of simplicity, etticiency and durability coupled with cheapness of cost in manufacture and installation.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claims.

In the accompanying drawings, Figure 1 is a fragmentary elevation of the inside of a car, showing my improved doors in closed position. Fig. 2 is a sectional vlew on the line 2-2 of Fig. 1. Fig. 3 is a perspective view of the locking device removed from the doors.

Referring now to the accompanying drawings in detail, the numeral 1 indicates a portion of the side wall of a railway car having the door opening 2 formed therein. Formed in the opposite side walls of the door opening 2 are alining sockets 3, 3, while suitably fastened to the inner wall of the car immediately adjacent to the side walls of the door opening are spacing strips l, 4 each of suitable height and provided with slots 5, 5 appropriately spaced apart, for a purpose which will presently appear.

- The numerals 6 and 7 designate the doors which are adapted to close the door opening, and these doors are capable of swingiug inwardly and outwardly of the door opening and are constructed of any suitable or de sired material. The doors 6, 'I are hingedly connected to the inner wall of the car adjacent to and at the opposite sides of the door opening and, if desired, each door may have hingedly connected to the upper edge thereof as at 8 an auxiliary section 9 whereby the height of the doors may be ll1C1tLSCCl when the occasion demands. tion between each door and the wa l of the car comprises, in the present instance, a pivot rod 10 secured to the wall of the ar through the medium of eye bolts 11, it and provided with oll'set portions l2, l2 terminating in pivot pins 13, 13 alining with each other axially and designed to be passed through eyes 15, 15 formed in the right angularly extending ends 1 (i, to of a securing strip 17 suitably fastened to the respective door adjacent to one side edge thereof. The offset portions 19, 12 of the pivot rods ll) are adapted to enter the slots 5, 5 in the spacing strips 41, t when the doors are in closed position, while the hinged edges of the doors rest against such spacing strips, thereby forming a tight joint between the doors and the respective wall of the car. From this construction, it will be seen that the doors may be swung inwardly of the door opening and against the inner wall of the car and may be also swung from the interior of the car to close the door opening, incident to the pivot rod swinging within the eye bolts 11,. ()n the other hand, should it be desired to swing the doors outwardly of the door opening, as when unloading the car, the pivot rods '10 will remain stationary, while the doors will, swing about the pivot pins 13, 13 which are carried by such rods and oil'set therefrom, the various positions being clearly illustrated by dotted lines in Fig. 2.

in order to reinforce the doors at their meeting ends when in closed position and to form a support for the auxiliary sections 9 when the latter are in use, a suitable reinforcing strip 18 is secured to the free edge of one of the doors, as the door (5.

To look the doors in closed position, that is to prevent outward movement of the doors under the action of the material within the car, I employ a locking device which, in the present instance, comprises a supporting strip 19 pivoted between its ends upon a pivot stud 20 carried by one of the doors, as the door 7, adj accnt to the free edge thereof, the free ends of the supporting strip 19 being provided with keepers 21, 21. Also pivotally mounted upon the stud 20 is a lever 22 and to the lever 22 are pivoted, at the opposite sides of the pivot stud 20, locking bars 23, 23 slidably disposed within the keepers 21, 21 and adapted to have the free ends thereof projected beyond the support- The hinged connecing strip 19 and into the sockets 3, 3 in the opposite side walls of the door opening. Thus, movement of the lever 22 in one direction projects the locking bolt into the sockets, while the reverse movement of the lever retracts the bolts, as will be readily understood.

From the foregoing description taken in connection with the accompanying drawings, the construction and mode of operation of my invention will be readily apparent, and while I have herein shown and.

described one preferred form of my invention by way of illustration, 1 wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims and without departing from the spirit of the invention.

I claim:

1. The combination with a Wall having a door opening therein and provided with alining sockets in the opposite side walls of the door opening, of a pair of doors adapted to close said door opening, and means for locking the doors against outward swinging movement, said means comprising a supporting strip pivoted to one of the doors and adapted to normally lie in a horizontal plane, keepers at the opposite ends of said strip, a lever pivoted on said strip approXimately centrally thereof, and locking bolts each having one end pivoted to said lever at the side of the pivot of the lever opposite from the other bolt, said bolts being slidably disposedwithin the keepers on the supporting strip and operable from said lever to be projected into and retracted from said sockets. V

2. The combination with a wall having a door opening therein and provided with alining sockets in the opposite side wails of the door opening, ofa pair of doors adapt-- ed to close said door opening, and means for locking the doors in the door opening against outward movement, said last means comprising a supporting strip pivotally mounted upon one of the doors, a lever pivoted upon said strip and adapted for swinging movement, locking bolts on said strip and connected to said lever and adapted to be operated therefrom whereby the free ends of the bolts may be projected into and retracted from said sockets. I

In testimony whereof I afliX my signature in presence of two witnesses.
